IMPRovgMEN-r 1N MACHINES Fon MAKme SHEET-LEAD.

Specification forming part of Letters Patent No. 115,730, dated June 6, 1871.

To all whom t may concern:

Ee it known that I, HENRY HANNEN, of Philadelphia, Pennsylvania, have invented a Method of Forming and Cutting Thin Sheets' of Lead; and I dovhereby declare the following to be a full, clear, and exact description of the same.

My invention consists inthe method, fully described hereafter, of obtaining thin sheets of lead, and oi" cutting the said sheets into lengths best adapted for conversion into white lead and for other useful purposes.

In order to enable others to make anduse my invention, I will now proceed to describe a mode of carrying-*the same into effect, referi ence being had to the accompanying drawing e 'short pipe or spout, C, iiattened at its outer end, and provided with a cock, a, and beneath and close to the flattened end of this spout is a wheel, D, whose spindle gis arranged to turn in uprights` 1 f, secured to a base, h. The lower portion of the wheel D turns in water contained in a vessel, F, and the periphery of the wheel, which is of a width corresponding to that of the sheets to be formed, has on each side a raised rim or ange, i, Fig. 3. K is a l blade, secured to adjustable arms j j, which project from ya-block, I, in such a manner that it can he maintained in close proximity to the periphery of the wheel at a point below the center of the same. A knife, H, .which extends acrcss the upper inclined surface of the block I, and by which the sheets of lead are cut, as will be hereafter described, is secured to one arm of a lever, k, which is hung to a rod, l., projecting from one of the uprightsf. The opposite arm of the lever is acted on by a spring, m, which tends to raise the knife H from the block, and is operated at regular in= tervals by an eccentric, p, of the spindle g, which depresses the knife.

In using the apparatus, a stream of molten lead, the supply of which is regulated by the cockfa, is caused to flow from the flattened end of the pipe C onto the periphery of the wheel D, where it is retained by the ilanges 'i i, which also serve to regulate the width of the sheets of lead thus formed. The wheel D turns in the direction of its arrow, and is prevented from becoming greatly heated by the water in which it is partly immersed, so that the sheet of molten lead spread upon its periphery is quickly cooled and is carried toward the blade K by the revolution of the wheel. If it be found, however, that, notwithstanding the partial immersion of the wheel in water, it becomes, after a time, too hot for use, two wheels may be placed side by side upon the the spindle g and arranged to slide upon the same, so that instead of suspending the operation one wheel can always be in use while the other is cooling. The blade K, which is in close proximity to the surface ofthe wheel, strips the sheet of lead from the same and directs it onto the inclined upper surface of the block I, and in passing over the latter the lead is cut into short pieces of an even length by theknife H, which de scends as its lever is operated by the eccentric p.

In place of the knife H, two rollers, t t', driven by gearing connected with the spindle g, may be employed. In this case the sheet of lead from the wheel passes between these rollers, and is cut through at each revolution of the same by a blade of the roller t, which enters a corresponding groove in the roller t. (See Fig. 5.)

Sheet-lead thus formed can be used for a variety of purposes, but it is especially adapted., when cut into short lengths, as above described, for conversion into white lead.

I claim as my invention, and desire to se cure by Letters Patentg l. The combination of the said flanged wheel,
